To all whom t may concern:

Be it known that I, LAWRENCE LANGNER,

This invention relates to improvements inf magnetos and has among 'its objects more particularly to provide an attachment lfor magneto machines which may be employed in connection with magnetos as placed upon the lmarket today by magneto manufac turers.

-This application is a division of my ap- Iplica-ation, Serial No. 790,968, filed Septemer 22, 1913, patented Mar. 19, 1918, No. 1,259,529. y

This device is so arranged that it may Ibe attached te or detached ,from an ordinary magneto, and the attachment comprises auxiliary electro-magnetic windings for increasing the intensity of the magnetic flux of the machine. Some preferred embodiments of the invention are illustrated in the accompanying drawings, in which:

Figures 1, 2 and 3 illustrate-three forms of electro-magnetic attachment in end elevation, the. parts being shown in section.

` In Fig. l, which shows a magneto of the Well known Boschl type, I have shown a detachable device in the form of 'a frame or sti'ap21, preferably of magnetic material', which -is adapted to fit over the permanent magnet 22 ofthe machine. This strap is bent around at each side thereof to form a housing 23 for a soft-iron core 24, and around this core and housing is arranged the Winding 3. The terminals 25 of the Winding 3 also serve for securing the attachment to the magneto. In Fie. QIthe detachable device is in the form o a nonmagnetic brass strap 21a, tied together at the upper end and bent to provide a housing to the magnets of an cr and thus -be utilized as an auxiliary excitation to increase the magnetic flu-x of thev forthe electro-magnet 3 which is mainmay form the strut 27* of soft iron 'and bend it as shown in Fig. 3 to form the core.

The binding posts 25 may serve as points of attachment for wires leading from any convenient auxiliary source of current, for

energizing the windings 3- of the detachable electro-magnets. Y .i

In the parent case, of which the present is a division, the auxiliary electro-magnets.

were energized b current from a. vbattery inv v a system Where t e magneto .is utilized. ignition device, and the batterycurrent'lead into the auxiliary magnets as an accompuit.

ment tothe operation of starting the gas engine in which the ignition system isused.v "This illustrates one advantageous inode of use of this detachable or auxiliary device vfor increasing the magnetism of the Vmagneto under certain conditions'.

The feature oit' the present 4application is that of having an attachable o r detachable auxiliary set of electro-magnetic windings, which may be superposed upon and attached ina magneto,

magneto., e

l/Vhile the form of mechanism herein shown vand described constitutes a preferred lforni of embodiment of the invention, it is to be understood that other forms might be adopted, all coming within. the scope of the claims which follow.

Vh-at I claim is':

1. In combination, a magneto including permanent magnets, with an attachment for increasing the intensity 4oma-gnetic flux of the magneto, said attachment being a unitary structure comprising a core, a Winding for said core, and mea'ns for detachably securing said attachmentl to the magneto.

2. In combination, a magneto having per-l vice comprising a unitary structure adaptedV to be. superposed upon the magnets of the magneto andv det-acliably secured thereon, sai structure being composed of a core arranged in parallel relation with the magnets and electro-magnetic f windings mounted upon Jche core. In testimony ywhereof I aix my signature. LAVREN-CE LANGNER. Witness:
